The MacBook Pro 15-inch (Mid-2017 Retina Display, Touch Bar, Four Thunderbolt 3 Ports) is powered by a 14nm, 7th Generation "Kaby Lake" Intel "Core i7" processor (7920HQ), with four independent processor "cores" on a single silicon chip, an 8 MB shared level 3 cache (SSD storage can be upgraded at the time of purchase, but the flash storage and Ram are both integrated to the logic, so cannot be upgraded later), and dual graphics processors -- either an AMD Radeon Pro 555 with 2 GB of dedicated GDDR5 memory or an AMD Radeon Pro 560 with 4 GB of dedicated GDDR5 memory as well as an integrated Intel HD Graphics 630 graphics processor that shares memory with the system.
